Message from Godfather of Sudoku

Thirty years have passed since the introduction of Sudoku into the world.
This unique puzzle has spread to over 140 countries, and remained rooted in more than 90 of them.
Here, we would like to launch a community for Sudoku as leisure activity for the mind, and not for monetary gain.
Let’s enjoy the richness and depth the game provides for your brain, body, and mind; nurturing the joy Sudoku brings to our daily lives.
To those who like Sudoku only a tiny bit, or to those who love it, you are more than welcome to join this community.

Congratulations on the launch of the Japan Sudoku Association!

I hope it continues the history of Sudoku, bringing pleasure to huge numbers of people.

My history with Sudoku began in 1997 when I bought a Nikoli book in a Tokyo bookshop. I didn’t really know what I was buying, but it didn’t take me long to get hooked on Sudoku. Then I took a different route to Nikoli, by making computer-generated puzzles.

But even though I took a different route, it’s always been a great pleasure to me that Nikoli has been very welcoming to me, and we have a long-lasting friendship.
